HYDROCARBON-BURNER.

Specification of Letters Patent.

Application filed December 9, 1902. Serial No. 134,475.

To all whom, it may concern.-

Be it known that I, WILLIAM H. THAYER, residing at Rogers Park, Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Hydrocarbon- Burners, of which the following is a specification.

My invention relates to hydrocarbon or vapor burners; and the object is to provide a simple, reliable, and comparatively inexpensive burner of this character containing improvements and features of advantage to increase the reliability and efiiciency of the burner.

' My burner belongs to that class in which the injector-orifice is unprovided with the usual needle-valve and a valve is employed in a supply pipe or passage not immediately adjacent the orifice. The principal objection to the valve-governed orifice is that the valve eventually wears the orifice to increased size or diameter, whereas the proper diameter thereof after being calculated should be preserved. The other class of valves have the objection of being liable to become clogged with sediment as to the injector-orifice. My burner is designed to overcome these objections by dispensing with the usual needlevalve, arranging a shut-off valve elsewhere, and providing a guard or strainer adjacent to the orifice, which guard can be readily removed for cleansing the burner. The injector-orifice is thereby effectually protected from foreign matter or sediment and not interfered with in any manner.

The several novel features of construction and points of utility of my burner will be apparent from the description hereinafter given.

In the drawings, Figure 1 is a side elevation of my burner, partly in section; Fig. 2, an enlarged elevation of the guard and plug to which it is attached; Fig. 3, a section thereof; Fig. 4, a plan of the plug, showing the injector-orifice therein; Fig. 5, a section on line 5 5 of Fig. 2, and Fig. 6 a view in half-section and elevation of a modified form of plug.

The burner-body 1 may be of suitable shape and construction, and, as herein shown, the same is provided with a burner proper or burner-cap (marked 2) of any usual or desired construction. The burner-body has a supplypassage 3, with which communicates a supply-pipe I, having any suitable valve 5 for governing the feed of the oil through the pipe. In the present instance the lower end of the burner-body is formed as a cylinder 6, having an interior chamber 7 communicating with the lower end of the supply-passage 8. The usual cup 8 is secured to or formed onto the lower end of the cylinder. In the upper end of the cylinder screws or fits a plug 9, which in the present instance has a knurled disk flange 10, although obviously the fiange need not be circular, but may partake of other shapes. The plug shown in Figs. 2 and 3 is externally screw-threaded, so as to screw into the cylinder 6; but,if desired,thescrew-thread may be dispensed with, as seen in the plug 11, (illustrated in Fig. 6,) and the plug pressed into an opening in the upper end of the cylinder. This plug has an injector-orifice 12 of the proper predetermined size. The plug has a central bore 13, communicating with the orifice 12 and into which is inserted an elongated strainer or guard of wire-cloth, consisting of a tube or cylinder 14, closed at the bottom by spinning or otherwise. The bore of the plug is, by preference, provided with fine threads 15, as best seen in Fig. 6, so as to better retain the guard, which consequently becomes a component part of the plug, and is therefore insertible and removable therewith.

The guard 14 may be of suitable size and shape and, as herein shown, the same is made by inserting an edge 16 of wire-cloth into the slot of a mandrel so as to become radial of the completed tube and winding the cloth therearound until the other edge overlaps, as seen in Fig. 5, thereby obtaining a simplymade and strongly-braced tube. WVhen the plug is in place, the guard depends into the chamber 7 of the cylinder in position to strain and filter the gas or vapor at the most desirable pointthat is, adjacent the orifice. The orifice is axially below the burner proper and also axially of the mixing-tube, which in the present instance is adapted to be removed out of the way to permit the removal of the plug and guard for the purpose of cleansing the parts or for any other purpose. As shown, the mixing-tube is made in .two sections 18 and 19, the lower one of which slides or telescopes within the other. The lower section 19 has a longitudinal groove 20, into which projects a set-screw 21, whereby this section of the tube may be thrust upward to permit the plug 19 to clear its lower end. The upper end of the groove contacting the setscrew prevents the lowering of the mixingtube below a predetermined point or level.

In practice the valve 5 is turned on for a moment and a small quantity of oil permitted IIO to overflow into the cup 8, which oil is ignited, as usual, to heat the parts of the burner. The valve is again opened, whereupon the oil will be vaporized atapoint adjacent the valve and in the passage 3. The gas then passes through the guard or strainer being thereby effectually cleaned, and is burned at the burner 2 in the ordinary and well-known manner. At intervals the plug and its attached guard are removed and the latter cleaned or renewed.

1. A hydrocarbon-burner comprising a burner-body having a burner proper and a vapor-supply passage, a flanged plug, provided with a central bore screwing into said passage and having an injector-orifice communicating therewith, and a cylindrical strainer secured in said bore of the plug and removable therewith, said' strainer consisting of a closed elongated tube adapted to filter through its side walls the vapor from said supply.

2. A hydrocarbon-burner comprising a burner-body having a burner proper and an injector-orifice in communication with a vapor-supply, and a strainer or guard arranged adjacent the orifice and consisting of an elongated tube of wire-cloth having an inner edge 16 extending inwardly and an overlapping outer edge 17.

3. A hydrocarbon-burner comprising a burner-body having a burner proper and a vapor-supply passage, a plug removably fitting into such passage and having a central bore and injector-orifice communicating with such passage, said bore having internal screw-threads, and a cylindrical strainer inserted in said bore and retained by said screwthreads.

4. A hydrocarbon-burner comprising a burner proper and a burner-body having a supply-passage 3 and a cylindrical chamber 7 intermediate of whose ends such passage communicates, a plug fitting in the upper end of said chamber and having an injector-orifice, and a guard or strainer secured to said plug and depending therefrom past such supplypassage and into the chamber 7.

5. A hydrocarbon burner comprising a burner proper and a burner-body having a supply-passage 3 and a cylindrical chamber 7 communicating therewith, a plug fitting in the upper end of said chamber and having an injector-orifice, and a cylinder 14 of Wirecloth secured to said plug and depending therefrom into the chamber 7.

6. The combination of a burner-body 1 hav- S. E. HIBBEN, LOUIS B. ERWIN.
